To all whomz't may concern:

'Be 'itknown'that I, ALLEN LooMIs, a Citizen of the United States, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful inggearing, which housing shall beaccesf sibleboth from the .front and from the top.

Another object of the invention is to construct a hydrocarbon motor having a crank shaft, a cam shaft, and an auxiliary shaft .triangularly arrangedvand driven by silent chain gearing, with an integralextension from .the crank case forming a housing around the chain gear mechanism, which housing is provided 4with. a removable top.

' cover, wherebythe clfain may be inspected vand removed vand replaced.

' Another object of the inventionis to form the top cover of the timing gear casingv of 'a hydrocarbon motor sothat it 'will form a lock for the supporting pivot pin of the motor crank Case. f

Another object of the invention is to form a cover-for the above construction so that it will also support the cooling fan-of the motor. 5 i i v. y

Another object of theinventionlis to provide- :i` motor vehic1e`crank case, in which the upper part is adapted to carry the upper half of .the -cranki shaft bearings, and in which a bottom bearing receiving member car-ries' the lower half of the'front' bearing of the Crankshaft and 'is formed -With' a forwardlyextending-wall, which forms the. 4:5 I i bottom of thenioto-r gear case..

in the l.following description, taken in con@ nection with the drawings which'orm a 55 part of this specification, and in v'vliicln-` igure 1l is a front elevation of a motor v v ehicle built in accordance with .this inven-- tion andhavingparts broken away; Fig. 2f@

is a vertical vlongitudinal sectional view 69" through the vehicle .shown in Fig. l, with some parts shown in elevation; Fig. 3 lis a section approximately -on the line 3-4-'3 of F1g. 2; Fig. 4 is a horizontal section'ap--f proxiinately on the line fle-f1 of Fig. 3; and 6L? Fig. 5 is a plan view of the parts shown Fig. 1, with the fan bracket removed. Referring to the drawings, 10 indicates'. one of `the side bars lof a motor vehicle frame, upon which the motor is mounted. 70 The motor illustrated is of the four cycle'. i

hydrocarbon type, having'its rear end suitably supported on the vehicle frame and having its front endpivotally 'supported on the framethrough. a' cross beam v11 and 'it pivot` pin 12, This pivot pin 12 'connecn the .cross member 11 with a bracket 13, which is securely" bolted to the upper part 14 of the crank case, `as by bolts 15. The;

pin '12 is retained in position, as shown in 80 Fig. 2, by means 'of a lug 16 formed as an integral part of a coverl?, which willbe hereinafter more -fullyndescribed k On the upper` part 14 of the crank case,

the cylinders -18 are mounted, and the crank 85 shaft 19 has its frontend 20 mounted. a bearing 21, the upper half of which is supported in the upper part 14; ofthe crank case, as shown particularly in Fig. 2. The lower half of the bearing 21' is supported 90 in abottom bearingA receiving member 22, which is secured to the upper part 14. by a pair ci` clamping pieces 23 and' bolts 24. The crank case or housing is completed by abottornv cover. 25, which is secured to the 55. upper part 14', and- .forms' a' joint with bearing receiving ineniberj 22 at 26, so that t the oil withinthe crank case cannot escape. 'The front walloffthe' crank'case is laterally y extended, ,as Shown@ a7 ina in,g )'30k A forwardly eiitending integral on the' member 22 forms the bottom".

V driving the same.

wall of this casing. This latter Wall is re movable, being secured to the other web portions, as by boltsv The wall 29 is somewhat farther extended to form a. wall 33, parallel with the wall 27, am! i, front cover 3i, which is also removable, is secured to the walls. as by bolts 35.

The front end 2O of the crank shaft extends forwardly, beyond its bearing, and hhs secured thereon a driving gear in the form of twin sprockets 3G. A sleeve 37 and nut 38 secures the sprocket in place, the.

sleeve being formed withhjaws 39, which cooperate with jaws At() on the end of the start-ing crank shaft ell, which Shaft mounted in al cup shaped member 42 secured to the cover 34. A spring keeps the jaws normally separated, and a crank Ll-l' is attached to the shaft 41 for manually operating saine. A cross member l5 of' the vehicle frame supports the forward end of the starting crank shaft4 il, as shown clearly in Fig.

Suitably niol'inted on the vehicle frame above the cross member 5, is a radiator 46 of any desired construction, and a fan 47 draws air through the radiator for increasing its eiiiciency. This fan is preferably operated by a belt extending from the pulley 4S, shown in Fig. 5, to the pulley i9, shown in Fig. 2, and the fan is rotatably mounted in an adjustable bracket 50, ha"- ingr a shank which is secured in a boss 52 formed integral with the cover l?, hereinabove referred to.

bearing member is rigidly secured to the wal] 2i", as by bolts 54, and this member is formed with a pair of separated bearings and 5G connected by webs 57, shown particularly in Figs. 3 and 4. In the bearings 55 anc 56 a shaft is mounted, which shaft projects through the wall 33 and has the pulley mounted thereon. Gears or sprockets 59 are keyed to the Shaft 58 for The shaft 58 is adapted to drive any suitable auxiliary mechanism of the motor, and is shown as operating a ccntri'uwl pump 60, the casing Si of which pump part of the hearing member thus pcrmittinp; the pump and bearing member to he cast and machined as a sinOle piece.

The motor cam shaft 6:2 is mounted in a suitable bearing in the wall 27 of the crank case and .it is provided with gear or twin sprocket 63, shown in dotted lines in Fig. l, and a chain Gl, preferably of the silent typo, connects the three sprockets 36, 59 and (i3, which sprockets are triangularly arranged for this purpose, as shown in Fig. 1.

Varioiis modifications of the invention may be made without departing from the spirit thereof, and the claims are intended to be of such scope esto cover all such modificatic-ns.`
